What is the primary focus and overall theme of Chapter 42 in the Sai Satcharitra?

Chapter 42 of the Sai Satcharitra begins with reverent salutations to Sai Baba, portraying him as a 'Wish-fulfilling Tree' for his followers. It briefly recaps miracles from the previous chapter, such as a portrait being miraculously protected from water and a devotee being guided in a dream to read the Dnyaneshwari. The main focus then shifts to describing Sai's nature and, most significantly, providing a detailed account of the events surrounding his departure from his physical body. As Chapter 42 explains, the purpose of sharing these stories is for the devotees' benefit, as remembering the Sadguru's feet dissolves obstacles and brings great holiness.
